Thanks for the info, that helps.
It seems she contacted you first, to come get things you left before you broke up. We do things like that

, it's an excuse to contact someone again when the time is right. And it seems she was and is still reeling from a fling. Now, if that fling left her hurt, she is calling you for comfort.
So she could be on the rebound, and you're the guy. Just because nothing physical has happened yet, doesn't mean she's not interested in you that way. She could just see you as a friend, someone to comfort you, or maybe she's testing the waters, trying to figure out if you're the one for her. I like what the other poster said, try the kino approach and see if she is at all responsive.
I'm not sure what you want from her. Do you want to get into a relationship again? Do you want a gf? Or do you want a casual hook up? If you want the latter, be careful. She seems vulnerable right now so she may not be the best target for now. I'm a girl (you could probably tell) and I'm not opposed to casual/FWB but I prefer if it's negotiated up front, so I don't get my feelings in a tangle.
